Licensing in London Borough of Hillingdon

Schemes are designated for a fixed period and are redesignated, widened or dropped. Treat this as the shape of the local regime and confirm the current designation on the council’s own licensing page before you let.

  • A licence is required where the HMO has five or more unrelated people living in it and two or more separate households
  • The council sets out the standing obligations alongside the licence: fire safety measures including working smoke alarms, annual gas safety checks, electrical checks every five years, no overcrowding, enough cooking and bathroom facilities for the number living there, clean and well-repaired communal areas, and enough bins
  • Letting a licensable HMO without a licence, or allowing more occupants than the licence permits, is an offence
  • HMO use can also need planning permission, which is a separate decision from the licence

Enforcement

The council’s own page still quotes the older £20,000 and £5,000 maximum fines. The current position is a civil penalty of up to £40,000, or prosecution, and the figures on this page come from the national duties table rather than the council’s page.

The duties that apply here whatever the council does

If you get it wrong

What letting without a licence costs

These are statutory, not local. A council that has designated a scheme can use all three, and a tenant can bring the second one without the council being involved at all.

Civil penalty
Up to £40,000Imposed by the council itself, without a prosecution. Serious or repeated breaches sit at the top of the range.
Rent Repayment Order
Up to 2 years’ rentThe tenant, or the council, applies to the First-tier Tribunal to have rent paid back. It is separate from the penalty above, not instead of it.
Prosecution
Unlimited fineLetting an unlicensed HMO, or breaching a licence condition, is a criminal offence and can be prosecuted rather than penalised.

Check your address

Three steps before you let the property

Designations are drawn by ward and sometimes by street, so the only answer that counts is the one for your address.

  1. Put the address into the council’s own checker

    It is the only source that is definitive for this borough, and it is the one the council will hold you to.

  2. Check the property against the national thresholds

    Mandatory HMO licensing is national, not local: five or more occupants forming two or more households need a licence wherever the property is, with no local scheme required.

  3. Get the evidence together before you apply

    Most applications ask for the same documents you already owe the tenant: the gas safety record, the EICR, the EPC, and the fire detection and escape arrangements for an HMO. The council’s list is the one that counts, but nothing on it will be a surprise if those are current.

FAQs

London Borough of Hillingdon: the questions landlords ask

What is the fine for an unlicensed HMO in Hillingdon?

The council can impose a civil penalty of up to £40,000, or prosecute. Some council pages still quote a £20,000 maximum, which later legislation overtook; a tenant can also seek a Rent Repayment Order of up to two years’ rent.

Does a 4-person share need a licence in Hillingdon?

No. Licensing starts at five or more unrelated people in two or more households. The HMO management regulations and every national duty still apply to a smaller share.
